I feel for these guys. I'm sure most of them joined this league as a last attempt to make it in the NFL. Sadly the owners know that and will exploit the shit out of them for it. It's the same stuff you see in minor league baseball.
Low pay means most players need an off-season job. Of course it would have to be a job that allows them to take 3-4 months off a year. Plus they have travel expenses. And not to mention putting their bodies on the line for this shot. It's not like college ball where at least they are getting an education. These guys are putting their lively hood on the line for $50,000. They deserve better assurances.
